Needles of Blackjack Pine, Bull Pine, Ponderosa Pine, Western Yellow Pine: Pinus ponderosa var. ponderosa (Synonyms: Pinus beardsleyi, Pinus benthamiana, Pinus brachyptera, Pinus ponderosa var. scopulorum, Pinus washoensis)

The photo above shows one bundle of three ponderosa pine needles, a characteristic of this species. The yellow-green needles measure 12-25 cm long. The female cones are symmetrical at the base and measure from 8-14 cm long. Photographed along the Island Springs Trail #66 on the eastern slopes of Mt. Adams..........August 25, 2005.

Photos of a fairly mature ponderosa pine seen along the upper section of the Island Springs Trail #66, Mt. Adams.........August 25, 2005. Mature ponderosa pines may attain heights of 70 meters. The bark at the base of older trees often turns cinammon red, becoming very thick with many layers of large plates of bark which can flake off fairly easily. Notice how the upper branches turn sharply towards the west, possibly the result of strong easterly winds (curing the winter?).
